[TYPO3-dev] Remove .svn folders from extension

[Søren Schaffstein]

Hi there,

I have recently switched my development environment and work with 
Subversion now. Doing this Subversion puts a ".svn" folder into each of 
my extensions folders to keep track of changes.

When I now save an Extension from the EM as t3x-file the .svn folders 
are included in this file.
Can I prevent this somehow or does anyone have a suggestion to do it in 
a better way?

Cheers,
Søren
